Commit 31fd85816d ("bpf: permits narrower load from bpf program
context fields") permits narrower load for certain ctx fields.
The commit however will already generate a masking even if
the prog-specific ctx conversion produces the result with
narrower size.
For example, for __sk_buff->protocol, the ctx conversion
loads the data into register with 2-byte load.
A narrower 2-byte load should not generate masking.
For __sk_buff->vlan_present, the conversion function
set the result as either 0 or 1, essentially a byte.
The narrower 2-byte or 1-byte load should not generate masking.
To avoid unnecessary masking, prog-specific *_is_valid_access
now passes converted_op_size back to verifier, which indicates
the valid data width after perceived future conversion.
Based on this information, verifier is able to avoid
unnecessary marking.
Since we want more information back from prog-specific
*_is_valid_access checking, all of them are packed into
one data structure for more clarity.

xdp: offload mode
While we discuss the representors.. :)
This set adds XDP flag for forcing offload and a attachment mode
for reporting to user space that program has been offloaded. The
nfp driver is modified to make use of the new flags, but also to
adhere to the DRV_MODE flag which should disable the HW offload.
The intended driver behaviour is:
DRV mode offload
no flags yes attempted
DRV_MODE yes no
HW_MODE no yes
Where 'yes' means required, and error will be returned if setup fails.
'Attempted' means the offload will only happen automatically if HW is
capable and offloading the program will cause no change in system
behaviour (e.g. maps don't have to bound).
Thanks to loading the program both to the driver and HW by default we
can fallback to the driver mode without disruption in case user replaces
the program with one which cannot be offloaded later.
Note that the NFP driver currently claims XDP offload support but
lacks most basic features like direct packet access.
Only change compared to the RFC is fixing the double bpf_prog_put()
which Daniel has spotted (patch 5).

Michael reported an UDP breakage caused by the commit b65ac44674
("udp: try to avoid 2 cache miss on dequeue").
The function __first_packet_length() can update the checksum bits
of the pending skb, making the scratched area out-of-sync, and
setting skb->csum, if the skb was previously in need of checksum
validation.
On later recvmsg() for such skb, checksum validation will be
invoked again - due to the wrong udp_skb_csum_unnecessary()
value - and will fail, causing the valid skb to be dropped.
This change addresses the issue refreshing the scratch area in
__first_packet_length() after the possible checksum update.

("RDS: TCP: Enable multipath RDS for TCP") is sent from rds_sendmsg()
before the first data packet is sent to a peer. If the conversation
is not bidirectional (i.e., one side is always passive and never
invokes rds_sendmsg()) and the passive side restarts its rds_tcp
module, a new HS ping probe needs to be sent, so that the number
of paths can be re-established.
This patch achieves that by sending a HS ping probe from
rds_tcp_accept_one() when c_npaths is 0 (i.e., we have not done

The patch stores the return code of the REQUEST_MAP_RSP sub-CRQ command
in the private data structure, where it can be later checked during
device open or a reset.
In the case of a reset, the mapping request to the vNIC Server may fail,
especially in the case of a partition migration. The driver attempts to
handle this by re-allocating the buffer and re-sending the mapping request.
The original error handling implementation was removed. The separate
function handling the REQUEST_MAP response message was also removed,
since it is now simple enough to be handled in the ibmvnic_handle_crq
function.

an application can later on get an fd based on the id through the
BPF_PROG_GET_FD_BY_ID command, and dump related prog info via
BPF_OBJ_GET_INFO_BY_FD command for bpf(2).

Pull more ufs fixes from Al Viro:
"More UFS fixes, unfortunately including build regression fix for the
64-bit s_dsize commit. Fixed in this pile:
- trivial bug in signedness of 32bit timestamps on ufs1
- ESTALE instead of ufs_error() when doing open-by-fhandle on
something deleted
- build regression on 32bit in ufs_new_fragments() - calculating that
many percents of u64 pulls libgcc stuff on some of those. Mea
culpa.
- fix hysteresis loop broken by typo in 2.4.14.7 (right next to the
location of previous bug).
- fix the insane limits of said hysteresis loop on filesystems with
very low percentage of reserved blocks. If it's 5% or less, just
use the OPTSPACE policy.
- calculate those limits once and mount time.
This tree does pass xfstests clean (both ufs1 and ufs2) and it _does_
survive cross-builds.
Again, my apologies for missing that, especially since I have noticed
a related percentage-of-64bit issue in earlier patches (when dealing
with amount of reserved blocks). Self-LART applied..."
